Answer:
a) 26.2
b) 13.8
Step-by-step explanation:
You add all side lengths, which are given.
a) 9+4.1+9+4.1 = 26.2
b) 3.6+3+7.2 = 13.8
The best thing to do is to find out what 1/5 is equal to, and you can do this by dividing $13.32 by 3
13.32/3= 4.44
Therefore, 1/5 = $4.44
As you're looking for the total amount, you multiply this by 5.
$4.44*5= $22.20
Therefore, the present cost $22.20

Once the rock hits the ground, we know that its height will be equal to 0m
because of this, we can replace H(x) with 0
now all we have to do is get x by itself
so..
then
now take the square root of each side

Answer:
a. When two variables change in the same direction, one remaining larger than the other by the same factor - direct relationship
b. To insert between neighboring points or estimate by taking an average of known values - interpolate
c. A relationship between two variables in which the product remains constant. When one variable increases the other decreases in proportion so that the product is unchanged - inverse relationship
The quotient is -8. This being because when a negative number is in parentheses, the negative will be the opposite: Positive. And we know 48 divided by 6 is 8. So the answer is B.
